Product Name: Embedded "G" Finned Tube Model NO.: Finned tube Connection Type: Welding Cross-Section Shape: Round Medium: Liquid Diameter: 25.4mm Standard: ASTM, GB, API, DIN, JIS Material: Carbon Steel MPa Classfication: Medium Pressure Piping Temperature Classification: Medium Temperature Piping Trademark: Paideer Transport Package: Plywood Box Specification: 16-63mm Origin: China HS Code: 8419909000 Product Description Bare tube general material: Copper, Alloy, Carbon Steel, Stainless SteelBare tube OD: 16-63mmFin general material: AluminumFin pitch: 2.1-5.0mmFin height: <17mmFin thickness: ~0.4mmG type finned tubeG type embedded spiral finned tube is processed from a certain width in the steel pipe and spiral groove depth, then inlaystheribbon on the steel pipebythe equipment.In winding process, asthe pre-tightening force to a certain extent sothe strip will be firmly in the spiral groove, to ensurethere isa certain contact area between steel band and steel pipe.In order to prevent the strip spring falling off the light tube, the twoends of the steel strip need toweld ontothe steel pipe.In order to set easily, there should bea certain clearance between steel belt and spiral groove.If the clearance is too smallthe settingprocess will bedifficult to proceed smoothly.In addition, the steel belt of winding there will always be a certain amount of rebound, whichmakes itcannot very good joint amongthe steel belt and spiral groove bottom. Inlaidfinscan be conducted on general equipment, and theycost little.Mcelroy companies in the United States the company I used the advanced production equipment, slotting embedding technology is advanced, from stable, embedded and firm, pulled off force not less than 70 n, the allowable temperature can reach 400ºC,has the strong ability of temperature resistance and thermal shock, widely used in petrochemical air cooler.
